l v `Moreivin'rnn LIGHT.

Appiication filed May 19,

'Ihis invention is a novel means for illuminating the inotometer in order thatfthe driver may readily readthe indications thereof at night.

Motometers. are placed upon@ theV radiator "cap and at night more oi lessdiiiiculty is encountered in reading the indications thereof even when sidelights upon the cowl of theautomobile are employed.

The object of my invention, therefore, is to provide an appaiatus whichwill direct a concentrated beam directly upon the motometer so that the indications thereof can be readily observed by the driver.

Another object of the invention is to provide a device which can be accurately adjusted upon the cowl of the automobile ir-v respective of the degree of inclination of the saine.

Another object of the invention is to so arrange the various parts that the source of light which is utilized for concentrating the rays upon the motometer can also be utilized for illuminating the underside of the dashboard and also directing the light to the foot controls and transmission lock of the automobile.

With these and various other objects in view the invention consists in the novel features of construction and the manner of combining and arranging the same all of which will be fully described hereinafter and set forth in the appended claims.

In the drawings forming part of this specification Fig. l is a view showing the practical application of my invention and Fig. 2 is a verticalsectional view of the same.

In carrying out my invention I employ a casing A which may be. of any suitable material and having an opening at the forward side thereof in which is located a concentrating lens B. To the rear of the concentrating lens is a reflecting mirror C. The lower portion of the casing indicated at D has the curvature of a sphere and fits into a socket ring E. The casing itself is preferably spherical in shape except at the front but the casing as a whole can be of any desired shape but as before stated. the lower portion thereof has the curvature of a sphere and in practice the `mirror C is arranged in a plane passing through the center of this sphere.

Threaded into the lower end of the casing is a sleeve F, this sleeve extending through 1926. Serial No. 110,682.

an opening G produced in the cowl I-I-of the automobile andl itA will be noted that this opening G is considerably larger than the sleeve F. Upon theinner' side ofthe cowl.

there. are arranged twol tapering washers I and K. through which sleeves` F passes and a nut L visscrewed upon the lower end n into the socket M, said socket having the conductor wires P leading therefrom.

Owing to the shape of the casing it can 1 i be properly adjusted in the socket ring and by means of the tapered washers an accurate adjustment can be had irrespective of the inclination lof the cowl H Vinasmuch as the openings through the cowl and the washers are sufficiently large to permit such adjustments vand then by tightening up on the binding nut L all of the parts are securely fastened together.

The rays of light emanating from the incandescent bulb pass upwardly through the. sleeve F and strike the reiiecting iniiror C and are directed .through the lens B and are concentrated. upon the motometer Vand it is for the purpose of permitting such concentration that the casing is given the spherical form and the two tapering washers provided together with the relative arrangement of the lamp mirror and lens.

In addition to providing the source of light for concentrating the rays upon thevv motometer ample. light will be` provided upon the rear side of the instrument panel and also the foot controls and transmission lock. v

It will thus be seen ythat I provide a simple and highly efficient device capable of carry` ing` out all of the objects hereinbeforey recited.

I-Ia'ving thus described my invention, what a reiiector, said casing also havingfan inwardly extending sleeve, a socket ring into.V which the casing fits and throughV which the sleeve passes', taperedV washers `through which the ring passes, :t nut upon the inner" end of said Sleeve, a bracket carried by the sleeve,Y

a socket connected to saidbracket and an incandescent. bulb fitted into said socket and having a` source of light in alignment with the sleeve, the openings in the washers-and socket ring being suiclent to permit angu lar adjustment of the Casing for the pur' pose specified.

2. In a. device of thekind` described,` tlle combination of zt cowl of an atuton'iobile,v of' a. source of llght arrangedupon the interiori of said cowl, a; casing arranged upon the exterior of' saudlcowl, said casing havmgu meansvincludinga tubular member in align mentwith thesource-oflight` 3. Inra device of the kind described, the combination oie cowl of an.aut0mobileof a casing provided with a reflector and a transparent lightV projecting Screen, said casing. having an opening in the bottom thereof, means for adjustably connecting saidoasing tosta-id cowl, said means includ- .ing tubular member, a bracket connected to said tubular member, a socket: connected to said-bracket and-'zt lamp arranged ill-said socket, said lamp beingy in alignment' with the tubular connection member and the openingfin the bottom of. the casing.

In testimony whereof, I' hereunto alli);`

my sigmtture.
